Leonard also commented on viewers' affection for the House/Wilson relationship.

"I'm glad that Hugh's and my work together has meant something special to people," he said.

"That does infuse the love of getting to work and doing it, and helps to support those days when you're kind of tired or down. I know how powerful that is, when you love a television show. But when it's your own show, it's different.

"It's like when someone says 'Hey, your sister's hot', and you're like... 'What? What are you talking about?'"
